Title: Device and method for detecting abnormality of pressure fluctuation absorbing mechanism
Inventor: NISHINO MITSUSHIGE
IPC: G01F1/00
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To prevent inaccurate measurement by detecting an abnormality of a pressure fluctuation absorbing mechanism. SOLUTION: When, for example, an output signal from a flow velocity sensor 51 is judged to include a signal negatively output largely beyond a specified value and thus a signal for a reverse flow of a gas flowing through a sensor flow path is judged to be output beyond a specified value by a sensor output judgment part 51a, an abnormality judgment part 81 judges that a pressure fluctuation absorbing mechanism is abnormal. When the pressure fluctuation absorbing mechanism is judged abnormal, an operation judgment part 82 controls a display control part 83 and a communication control part 85 so as to notify the outside that it is abnormal and, as required, controls a shutoff valve control part 84 so as to close shutoff valves 21 and 22. Thus inaccurate measurement is prevented from occurring.

Title: Injection control method of direct injection internal combustion engine
Inventor: SHIMADA MASANORI
IPC: F02D41/04
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To reduce a rate of fuel stuck on a cylinder wall by injection fuel while regulating an air-fuel ratio to a lean side more than a theoretical air-fuel ratio in a compression stroke in the case where a detected temperature of an internal combustion engine is not more than a predetermined temperature, in a device wherein fuel is injected in the compression stroke and an intake stroke according to an operating condition. SOLUTION: During operation of an engine 10, a cooling water temperature and a predetermined water temperature which is set beforehand are compared with each other, and it is judged whether an engine is warm-operated or not. At the time of the warm operation, fuel is injected by a fuel injection valve 8 in a compression storke by regulating an air-fuel ratio to a lean side more than a theoretical air-fuel ratio. On the other hand, at the time of an operation after warm operation, fuel is injected according to an operating condition of an engine. Namely, fuel is injected in the compression stroke at low and intermediate loads and in an operating condition in which engine rotating speed is a middle state.  Fuel is injected in an intake stroke in an operating condition of a high load with low and intermediate engine rotation extending a region of compression stroke injection, and in a high rotating operation condition. It is thus possible to reduce fuel quantity sticking on an inner wall surface of a cylinder 4a.

Filed: 1994-12-27
Abstract: PURPOSE: To measure a physical/chemical quantity at a low cost without depending on the influence of the temperature by always obtaining a polarization analysis modulation signal from at least one of optical detectors by means of a structure provided with a plurality of polarizing filters. CONSTITUTION: A polarization modulated optical signal L is incident, for example, on a beam splitter ST from a magneto-optical Faraday rotator with the linear polarization direction P. The polarization direction P is provided with a polarization angle α (t) toward a mean position of a polarization face α0. The light signal incident on the beam splitter ST is separated into two partial beams so as to reach the first and the second detectors D1, D2 via the first and the second polarizing filters P1, P2 which cross each other orthogonally. The detectors D1, D2 convert light output signals S1, S2 into a voltage and a digital signal proportional to the voltage on the output side and feed out them to a microprocessor 1 for evaluation.  The microprocessor 1 outputs a modulation signal S, which does not depend on the condition of the polarization face α0, so as to feed it to a command device 2.
